ADV7202KST - 12-Bit 5-Channel Video Codec | Analog Devices
MPN： ADV7202KST ✗ 停產ADV7202KST 概覽
A video codec is a mixed-signal interface IC that converts analog video into digital data and can also produce analog video outputs. In the signal-processing hierarchy, the ADV7202 belongs to the codec family, interface IC class, and broader data-conversion semiconductor category. Its five-input capability allows one device to support several standard-definition video sources, while its four DAC outputs support reconstruction or monitoring paths.
The principal verified features include simultaneous sampling of up to five composite video inputs, 12-bit front-end digitizer resolution, four video DAC channels, and 12-bit/10-bit digital data capability. The package is specified as 64-pin LQFP, also described in search data as PQFP64 or plastic LQFP-64. This integration can reduce the number of separate converters required in a video system, although exact timing, voltage, clock, output-format, and thermal details must be confirmed from the manufacturer documentation.
The architecture is suited to systems that need a consolidated analog-video interface rather than discrete converters. Simultaneous sampling is important when multiple composite signals must share a defined acquisition moment, while the multiple DACs provide parallel analog-output capability. Digital resolution, clocking, sync handling, and supported video standards remain critical system constraints that depend on the selected operating mode and the complete ADV7202 datasheet.
Typical uses include professional video test equipment, broadcast video monitoring, surveillance-system interfaces, video capture hardware, and multi-source analog-video switching systems. The component is particularly relevant when the board must ingest multiple composite video streams and retain flexible digital processing before conversion back to analog. Product selection should also account for source format, required resolution, supported clock, interface voltage, thermal conditions, and system timing.
A practical design review begins with the ADV7202 datasheet pinout, electrical tables, timing diagrams, and application guidance. PCB layout should preserve analog and digital return paths, provide appropriate decoupling, and route high-speed digital signals with controlled impedance. Since the verified data does not include complete pin assignments or operating limits, engineers should not infer those values from generic codec designs.
This page combines verified product, package, interface, and sourcing information with transparent data gaps, procurement guidance, and application-oriented engineering context. It distinguishes confirmed ADV7202KST facts from unverified parameters so designers can evaluate the codec efficiently without mistaking distributor summaries for a complete datasheet.

典型應用
ADV7202KST 適用於 6 應用s: Broadcast Video Monitoring, Surveillance Video Interface, Video Test Equipment, Multi-Source Video Routing, Analog Video Capture, Security Video Diagnostics.
Broadcast Video Monitoring
ADV7202KST fits a broadcast monitoring subsystem that accepts up to five supported NTSC, PAL, or SECAM composite sources. Its simultaneous-sampling codec architecture combines one ADC with four DACs, allowing captured video to be digitized and reconstructed for display or signal-quality analysis. The 12-bit front end includes two bits assigned to gain and offset adjustment, providing control range for signal conditioning. The 64-pin LQFP supports integration on a multilayer board, but exact clocking, signal levels, timing, and electrical limits must be confirmed from the manufacturer datasheet before layout.
Surveillance Video Interface
ADV7202KST is applicable to surveillance equipment handling several composite camera feeds because it can sample up to five NTSC, PAL, or SECAM inputs. Simultaneous acquisition can simplify systems that compare, record, route, or switch multiple video streams, while four DACs can provide analog reconstruction or monitor outputs. The confirmed 12-bit front-end resolution supports signal acquisition, while two bits are reserved for gain and offset adjustment. Deployment still requires validation of input bandwidth, synchronization behavior, operating temperature, and supply conditions not supplied in the verified snippets.
Video Test Equipment
ADV7202KST can serve as the central video conversion element in bench or rack-mounted video test equipment. Up to five composite inputs can be selected for acquisition, converted through the codec's ADC path, processed digitally, and returned through four DAC outputs for comparison or display. This integrated path may reduce the component count associated with separate converters when all signals satisfy the supported video formats. Engineers should verify clock frequency, sample-rate requirements, synchronization, output coding, and calibration controls against the complete Analog Devices documentation before instrument development.
Multi-Source Video Routing
ADV7202KST fits multi-source routing equipment built around composite video because it accepts up to five NTSC, PAL, or SECAM inputs and provides four DAC channels. A control processor can capture selected sources, perform system-specific processing, and route reconstructed analog video to downstream equipment. The single ADC and four DAC arrangement may simplify board partitioning compared with a larger collection of unrelated converters. However, switch timing, channel latency, signal-level compatibility, and whether all five inputs operate simultaneously in the required mode must be confirmed from the full datasheet.
Analog Video Capture
ADV7202KST is suitable for an analog-video capture front end when the source conforms to one of the supported NTSC, PAL, or SECAM systems. Its 12-bit front-end digitizer can feed a downstream processor, image-capture engine, or storage pipeline, while two bits provide gain and offset adjustment for signal conditioning. The four integrated DACs add flexibility for local analog monitoring. Board design must preserve analog signal integrity, provide suitable reference and decoupling networks, and verify input bandwidth and clocking against the manufacturer's complete electrical tables.
Security Video Diagnostics
ADV7202KST can support diagnostic functions in professional security-video equipment by acquiring up to five composite feeds and generating four analog outputs for comparison or monitoring. Simultaneous sampling is useful when signals must be captured under a common timing reference, and the 12-bit front end provides the stated conversion resolution. An external processor can perform image-quality checks, channel comparison, event logging, or overlay generation. Exact timing tolerance, synchronization standards, signal conditioning, and operating limits must be established from official documentation before production use.

設計說明
Treat the five composite-video inputs as sensitive analog paths even though the output is digital. Use the manufacturer's recommended input network, grounding, and reference topology rather than inferring values from generic video circuits. Keep analog traces short, isolate clocks and digital outputs from input nodes, and provide a quiet return path. The supplied data confirms signal-format and resolution capabilities but does not provide input impedance, bandwidth, recommended termination, or reference values.
Before schematic capture, obtain the complete ADV7202 datasheet and verify all 64 LQFP connections, exposed-pad requirements, supply pins, analog grounds, digital grounds, clock inputs, reference voltages, control pins, and output coding. The verified web results confirm only the 64-pin LQFP package, not individual pin assignments. A generic LQFP-64 symbol is unsafe because missing power, ground, or analog-signal pins can prevent operation or degrade video performance.
Do not interpret the 12-bit front end as twelve freely adjustable signal-processing bits. Analog Devices states that two of the 12 bits, equivalent to 12 dB, are used for gain and offset adjustment. Also distinguish front-end resolution from the distributor-reported 12-bit/10-bit digital capability. Confirm the supported output format, clocking scheme, and operating mode in the datasheet before sizing downstream processors and digital interfaces.
Confirm every supply rail, analog-reference voltage, sequencing requirement, and decoupling value from current Analog Devices documentation. The supplied search snippets contain no supply-voltage figures, current limits, or power dissipation data, so no capacitor or regulator sizing can be safely derived. Apply separate clean return paths for analog and digital sections where the manufacturer layout guidance calls for them, and verify ground-reference relationships to avoid injecting converter noise into the video inputs.
合規資訊
The supplied product and distributor search snippets do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements.
